Damn firewalls. However as I see the graph, the points are lined up exactly on the centreline of each boxplot. So for example the lowest outlier on grp1 boxplot for A is exactlly where it should be at the end of the whisker. Real outliers for grp1 for D are exactly above the 'non-existant' whisker for that boxplot. So I looks to me as if in my version of the plot it is what you want.
Any change that I can email directly to you and get an attactment through?
